I've got two tables and need to obtain the data in the Records table based on the information in the RecordsNeeded table. For example:
Member 123 has records in the Records table between 2004 and 2015, but I only need the records that are defined in the RecordsNeeded table which would be Member 123 FromYear = 2013 and ToYear = 2015
Member 456 has records in the Records table between 2001 and 2015, but I only need the records that are defined in the RecordsNeeded table which would be Member 456 FromYear = 2008 and ToYear = 2015
CREATE TABLE [dbo].[Records](
[MemberID] VARCHAR(12),
[Year] SMALLINT,
[Field1] [VARCHAR](50) NULL,
[Field2] [VARCHAR](10) NULL,
[Field3] [VARCHAR](10) NULL
) ON [PRIMARY]
CREATE TABLE [dbo].[RecordsNeeded](
[MemberID] VARCHAR(12),
[FromYear] SMALLINT,
[ToYear] SMALLINT
) ON [PRIMARY]
I hope this makes sense, thanks..

This should give you a starting place:
SELECT R.MemberID
FROM Records R
INNER JOIN RecordsNeeded RN ON R.MemberID = RN.MemberID
AND R.Year BETWEEN RN.FromYear TO RN.ToYear
